One to add to the MAYBE list - THE ONLY GOOD INDIAN ( http://www.theonlygoodindian.com ). Although the use of horror is more metaphorical than literal in this film - Bram Stoker's novel of DRACULA is referenced throughout the film; although if you're Native-American, you could consider it a horror story along the lines of THE NIGHT OF THE HUNTER. The film can be seen via Netflix streaming.
